Summary: Bought a used core 2 duo processor e6700 from this seller (Eagle Eye) for $14.95 to replace a sluggish Pentium D 820 in an old HP desktop. The shipping was real fast with great packaging and even included enough thermal paste for one application. The e6700 looked like new, very clean.
Summary: Upgraded my old OptiPlex 745 with this. It's the best Core 2 Duo for this machine. It works great. Don't be afraid to buy used from these folks. Have gotten excellent service and items arrive early - I love early.
Summary: My older computer BIOS only recognizes the 2.66 GHz CPU max. When I ordered, I was surprised that I was shipped a 3GHz CPU. Normally this would be a good thing, but in my case it wasn't recognized. A call to the shipper and a new 2.66GHz chip was on its way the next day. The 2.66GHz worked perfect.
